Abstract

L'invention concerne un capteur optique à codage de modulation spectrale fonctionnant en réflexion, qui est relié par une fibre optique (10) à une source de lumière et à un démodulateur, et qui comprend une lentille de collimation (16), un premier polariseur (18), un élément sensible (20) soumis à la grandeur physique mesurée, un second polariseur (32) et un moyen catadioptrique de réflexion (28), tel qu'un coin de cube. Le capteur selon l'invention permet une réinsertion totale du flux lumineux dans la fibre optique (10) après la traversée du capteur, sans aucune perturbation du phénomène d'interférence.
